I have received offers of lower prices, from the SP herself. These though are for your longer dates, which can include dinner dates. But the offer comes from her, without you implying or asking for any lowering of her posted fee, for the same event. For any SP, you look at her rates, and decide if they are acceptable, or not, to you personally. Some SP's social time, and bed time, can be the same. Doubt if many get that many offers, for longer appointments. But that is their choice, to make. Other decide that they enjoy the social time, and the rates reflect that. But for an hour or less, why would she lower her rate, for a more brief encounter. If you do mot like the posted rate, move on to another. There is not a shortage, so you should find one who's rate is in line, with your expectations.
